Title: Improvements in ratchet mechanisms
IPC: F16H31/00
Filed: 1949-02-22
Abstract: 661,688. Ratchet gearing. UNITED ENGINEERING & FOUNDRY CO. Feb. 22, 1949 [June 19, 1948], No. 4823/49. Class 80 (iii). A ratchet mechanism, particularly suitable for the feeding mechanism of machine tools, comprises a driven sleeve 24 and ratchet wheel 25, a driving pawl 61 carried on a rocking arm 21 and a hydraulic actuating piston and cylinder 37, 36. Fluid pressure is alternately supplied to and exhausted from the cylinder 36 by means of valves operated by cams on a machine shaft so that the arm 21 is rocked in one direction by the fluid pressure against springs 54, 55 and in the other direction by the springs. The engagement of the pawl 61 with the ratchet wheel 25 is controlled to vary the rate of feed imparted to a tool 16 through a screw 33 by means of a control pawl 62 rotatable with but slidable axially on the shaft 59 of the main pawl 61 and co-operating with a series of control ratchet wheels 84-93 frictionally mounted upon a sleeve 95. Each of these wheels has the same number of teeth which is comprised of a number of shallow teeth 119, Fig. 8, and a number of deep teeth 121 which are different for each wheel. The arrangement is such that when the pawl 62 is engaged with the .shallow teeth 119 the control wheel is advanced one tooth but the main pawl 61 is held out of engagement with the teeth of the wheel 25. When the pawl 62 moves into a deep tooth 121, however, the pawl 61 engages the teeth of wheel 25 to advance sleeve 24 one tooth also. Thus the rate of feed imparted depends upon the frequency of the deep teeth 121 around the wheels 84-93. The desired control ratchet is selected by sliding the pawl 62 along the shaft 59 of the main pawl 61 by means of a fork member 72 of a nut 74 on an adjusting screw 75, Fig. 7. The screw 75 has an adjusting knob 81 with a scale 82 indicating the adjusted rate of feed. When changing the pawl 62 from one control wheel to another the pawl is lifted by means of a lever 106 rocking a shaft 104 which has a slot 105 therein receiving a curved arm 100 attached to the pawl 61. A number of such mechanisms may be arranged on a lathe to operate separate tools and be actuated from a common pressure fluid supply pipe.

Title: An improved apparatus for laying concrete-reinforcing metal fabric
Inventor: HOWARTH CHARLES HENRY
IPC: E01C23/04
Filed: 1954-02-19
Abstract: 766,773. Reinforced concrete; paving. BRITISH. REINFORCED CONCRETE ENGINEERING CO., Ltd. Feb. 4, 1955 [Feb 19, 1954], No. 4880/54. Class 20(4) In the laying of con. crete roads and runways, the metal reinforcement fabric is supported, during the application of the concrete, at the required height above the bottom of the concrete, by arms which are withdrawn, after consolidation of the concrete, for use on another, e.g., the next, section of road. Fig. 2 shows the metal reinforcement fabric 11 supported on blades 10 which are tapered from, say, four inches to two inches, to facilitate withdrawal from the concrete. The blades 10 are in pairs, each pair being rigidly connected to a V-shaped draw bar 12, the assembly being supported by rollers 15 which are adjustable vertically to determine the height of the reinforcement. The spacing of the pairs of blades is determined by the width of the road, this spacing being permitted by the attachments of the draw bars 12 to a cross-member 16 which is mounted, at each end, on wheels 22 running on a track 24. The attachments each comprise a clamp 17 having tightening bolts 19 which serve as a pivotal connection for brackets 20 on the draw bars 12. The,brackets 20 are angularly positioned by screws 21. An operating platform 27 is carried on the cross member 16. The reinforcement-supporting equipment may be provided with its own traction power, or may be coupled to the concreting machine 23 to move therewith. The tendency of the falling concrete to depress the blades 10 by pivoting on the rollers 15, may be countered by supporting the reinforcement, when it is in the form of a roll, upon the draw-bars 12. Alternatively, the cross member 16 may be sealed and filled with water. When expansion joints are to be provided, suitable prefabricated shuttering is used just after the rollers.15 have passed the point where the joint is to be. Alternatively, a tilting arrangement could be provided for lifting the draw bars and blades over the expansion joint shuttering,
